Detailed Description
The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without any inventive effort, are intended to be within the scope of the invention.
As shown in fig. 1 to 6, a novel shield main machine with a variable section comprises a shield head 30, wherein a cutting system 10 and a hydraulic lifting system 20 are arranged on the shield head 30, and a lifting chute 301 is arranged on the shield head 30; the cutting system 10 comprises a cutter disc 101 and a transmission shaft 103, wherein the transmission shaft 103 passes through a lifting chute 301 and then is connected with the cutter disc 101; the hydraulic lifting system 20 comprises a hydraulic cylinder 201, a base of the hydraulic cylinder 201 is fixed on the shield head 30, and a push rod of the hydraulic cylinder 201 is connected with the transmission shaft 103.
The front end of the push rod is provided with a fastening part 202, and the fastening part 202 is contacted with the transmission shaft 103.
The fastening part 202 is provided with an arc-shaped groove on the inner side, and the radian of the arc-shaped groove is matched with the transmission shaft 103. The base of the hydraulic cylinder 201 is fixed to the shield head by a fixing member 302. The arrangement of the arc-shaped groove prevents the slipping phenomenon when the push rod of the hydraulic cylinder pushes the transmission shaft 103.
The lifting sliding chute 301 is a strip-shaped through chute.
One end of the transmission shaft 103 passes through the center of the cutterhead 101, and the other end is connected with the motor 106.
The cutterhead 101 is a spoke cutterhead, and the spoke cutterhead has at least two layers.
Two hydraulic cylinders 201 are symmetrically arranged on two sides of each transmission shaft 103. The hydraulic lifting system realizes the change and fixation of the position of the transmission shaft by propping up the fastening parts 202 which are in clearance fit with the transmission shaft 103 by the hydraulic cylinders 201 symmetrically arranged on the two sides of the transmission shaft.
A bearing 104 is arranged between the transmission shaft 103 and the lifting chute 301, and a motor 106 is connected with the transmission shaft 103 and provided with a belt speed reducer 105. The lifting chute 301 is a chute with one dimension up and down or left and right, and cooperates with the bearing 104 to restrict the transmission shaft 103 to move up and down and left and right at the same time, so that the transmission shaft 103 can only have one degree of freedom in up and down and left and right movements.
The hydraulic cylinder 201 of the hydraulic lifting system 20 stretches and pushes the transmission shaft 103 to move in the lifting sliding groove 301, so that the cutting track 107 of the cutterhead is changed, and further, the cutting shape is changed arbitrarily, such as a round shape, a horseshoe shape, a rectangular shape and the like. The arrangement of at least two layers of spoke-type cutterheads 101 avoids interference between the spoke-type cutterheads 101 due to the fact that the lengths of the transmission shafts 103 extending out of the shield heads 30 are different, and the problem of mutual interference of cutterheads in the process of adjusting different cutting shapes of the cutterheads can be solved through the extending lengths of the spoke-type cutterheads 101 of a plurality of layers. According to the invention, the cutter disc 101 and the transmission shaft 103 are sequentially connected with different extending lengths from bottom to top, the transmission shaft 103 is matched with the bearing 104, and the bearing 104 is installed in the lifting chute 301 on the shield head 30. The hydraulic lifting system 20 is then fixed to the shield head 30 by means of a fixing element 302 which fixes the hydraulic lifting system. The fastening member 202 of the hydraulic lifting system 20 is engaged with the transmission shaft 103 to restrict the movement of the transmission shaft 103, and the pair of hydraulic cylinders 201 are connected to the fastening member 202 to move the position of the transmission shaft by lifting and lowering the pair of hydraulic cylinders. The speed reducer 105 is connected with the transmission shaft 103, and then the speed reducer 105 is connected with the motor 106 to form a complete power system.
As shown in fig. 3, a cutting surface shape embodying the present invention will be described as an example: 301 is a lifting chute, 107 is a single-blade disc cutting track with a single-blade disc cutting area shape, 108 is a multi-blade circular envelope track with a multi-blade cutting surface track, namely, the cutting area shape formed by multi-blade combined work. The transmission shafts corresponding to the lower three cutterheads are lifted for different displacements in the lifting sliding chute through the hydraulic lifting system, so that a multi-cutter-disc horseshoe-shaped envelope curve track 109 of the multi-cutter-disc cutting surface track shown in fig. 4 is formed. Still further, the transmission shafts corresponding to the lower three cutterheads are lifted for different displacements in the lifting chute by the hydraulic lifting system, so as to form a multi-cutterhead rectangular envelope track 110 of the multi-cutterhead cutting surface track shown in fig. 5.
